[APD] RE: Why algae don't grow and plants do under non limiting conditions
I agree with Tom about algae not being weenies. "Darwinian weenies" are extinct, not
thriving in virtually every aquatic and terrestrial ecosystem on earth. Species poorly
adapted to their environment just don't last, so you can assume that if it does
something we think isn't advantageous then it probably means we don't really
understand why it does what it does. In its preferred habitat it probably has some
advantage over species that do things a different way. This isn't to say evolution is
perfect, in fact every organism is stuck with some anachronistic characteristics they
don't need but aren't selected out of the species for one reason or another. But
something as fundamental as physiological responses to different forms of N are
pretty significant. Keep in mind that even the simplest bacteria have been evolving
just as long as we have!
P.S. Does anyone know how to get Yahoo mail to wordwrap? My posts will be one
long line on the APD page if I don't hit return, but Yahoo mail puts a big space
between lines if I manually return. I feel damned if I do and damned if I don't!
